The vulnerability identified as CVE-2025-62907 affects the Custom Post Type Attachment plugin from aviplugins.com, specifically versions up to 3.4.6. It is a stored cross-site scripting (XSS) flaw caused by improper neutralization of input during web page generation. This allows an attacker with at least low privileges and requiring user interaction to inject malicious scripts that can execute in the context of other users, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS vector indicates network attack vector, low attack complexity, privileges required, user interaction required, and scope change. No patch or official remediation guidance is currently documented.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of users viewing the affected content, potentially leading to unauthorized actions, data disclosure, or disruption of service. The CVSS score of 6.5 reflects medium severity with impacts on confidentiality, integrity, and availability. However, no known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
